To all whom it may concern Be it known that 1. CHARLES P. Axonnson, acitizen of the llnited States, residing at Seattle, in the county ofKing and State of \Yashiugton, have invented certain new and usefulImprovements in Combined Measurinn and Locking Devices for Valves, ofwhich the following is a specification.

This invention relates to valves such as are employed for dispensingliquids and has particular reference to the valves of irrigat ingsystems.

The object of the present invention is the provision of convenientlyoperated and reliable means whereby a valve may be regulated to ati'ordpassage for a selected flow of liquid and also to provide means forsecuring the valve in such predetermined positions.

Vith these ends in view, the invention con-' scribed with reference tothe accompanying drawings, wherein According to the present invention,the bonnet 7 is formed with or'has secured thereto a bracket-element 12through which extends an opening 13 to serve as a guide for the stem llof a T-shaped measuring device having at its top oppositely directedbranches or arms 15 and 16. The branch 15 is-provided with a hole 17 toreceive the valvespindle 6 and the other arm 16 is provided with a hole18 to receive the bow 19 of a pad? lock 20 when the same engages thehandwhecl S. as shown in Fig. 1; The branch 15 of said measuring deviceis held against the wheel-hub 8 by any suitable means such as a shoulderprovided on the spindle or, as shown, by means of a pin 21 inserted in ahole provided in .the spindle below the branch 15. Said stem is providedwith graduated marks 22 which are arranged to register with the topsurface of the guide or bracket 13 to indicate the amount of the.

valve opening.

The device may be adjusted to compensate for wear and with respect tothe scale mark- Figure 1 is a view in vertical section of iv-"Hugs byregulating the position of the seat 4 valve with my invention appliedthereto.

Fig. 2 is a plan view of the same with the lock omitted. Fig. is aperspective view of the gage member.

The valve body 1, as illustrated, is formed with an exteriorly threadedoutlet 2 and an inlet provided with internal threads to receive thecoupling 3 having internal threads for engaging with a supply pipe. Theend} of the coupling 3 which extends into said body is machined to serveas aseat for the valve proper; in practice said coupling is made ofbrass or other metals which will withstand the corrosive action due toalkali or other chemicals carried in water.

The valve 5, in the illustrated example, is of the disk-type and hassecured to its underside a disk 5 of leather or other suitable yieldingmaterial to make a tight closure with the referred to seat.

(3 represents the valve spindle extending relatively to the valve byscrewing the couplinr 3, as may be required, into or out of the socketprovided therefor in the valve body.

The measuring device is connected with the spindle to travel with thevalve, when the latter is moved through the instrumentality of thehand-wheel, and may he socured in selected positions by means of thepadlock, as before explained. The gradu ated scale registers zero whenthe valve is closed, and as the valve is withdrawn from its, seat, thescale registers the amount of opening or the effective area of thepassage for the flow of water or other liquid.- By means of themeasuring device, the flow may be readily determined thus:-for example,assuming), that the scale of the measuring device indicates that thevalve is raised to afford an opening having an area of three inches atwhich it remains for twelve hours with a substantially constant head,then with these elements known-- that is, time, pressure and area-thequantity of water passing the 'alve can be calculated.

The advantages of the invention reside, principally, in the facilitywith which h amount of water delivered through the valve may bedetermined and also in the provision of improved means whereby the valvemay g l I 1,169,906

be locked in adjusted'p0sition' by ordinary padlock.

Having described Iny invention, what-I.

claim, is' 4 5 1. The conibina'ltion with'a valve provided with aspindle and a handwheel, of a measuring-device connected with saidspindle to move axially therewith and indicate the extent the valve isopened and a perforated arm provided on said ineasiu-ing'd'evice toengage ailockwhereby said measuring de-' :VICG- may be locked to saidhandwheel to .prevent rotation thereoff 2.1a apparatus of the classdescribed, a valve-spindle, ahand-wheel therefor, a T- shaped devicehaving a stemand two branches. one of said branches beingcon nected withthe valve-spindle and the other 1 branch ,being a'dapted to be connectedby means ofa padlock to' said hand-wheel to prevent the latter beingrotated. .3. In apparatus of the class described having a' rotaryvalve-spindle and a handwheel secured to said spindle for operating thevalve, of adevice connected with the spindle to travel therewith in anaxial direction only, and means engageable with both the device, and thehand-wheel to secure the spindle against rotation. v 80- 4. In apparatusof the class described, the
